• Warnings: Avoid freeze/thaw cycles.
• Category: Demethylase/Enzymes
• Background: Histone demethylase that demethylates Lys-4 of histone H3, thereby playing a central role in histone code. Does not demethylate histone H3 Lys-9 or H3 Lys-27. Demethylates trimethylated, dimethylated and monomethylated H3 Lys-4. Acts as a transcriptional corepressor for FOXG1B and PAX9. Favors the proliferation of breast cancer cells by repressing tumor suppressor genes such as BRCA1 and HOXA5. In contrast, may act as a tumor suppressor for melanoma.
